Recognizers

This package is a collection of recognizer
examples. To play with them, simple implementations
for (old) gforth and VFX are included.
These words are not (yet) able to compile code
or are otherwise integrated into the underlying
system.

Recognizer*.4th

These files in combination with Stack.4th give a
playground for making experiments with recognizers. They
have been tested with gforth versions that usually
come with the linux distributions and MPE's vfxlin (a
random older version from 2014).

The files Recognizer-gforth.4th and Recognizer-vfx.4th
differ in two aspects only. First is the tester framework.
Gforth supplies the T{}T words while vfx has the
older {} pair (and a slightly different filename
to be used). Second is the implementation of
the number recognizers which use existing words that
differ alot.

literacy.4th

Simple formatting of source code in the
spirit von Don Knuth literate programming. You can
combine the real source code and its documentation
in one document that the standard forth interpreter
can handle directly.
